Section 9 is formed with a series of longitudinal fail to register withthe opening I8 in the strike plate due to sagging of the door or otherconditions, it is merely necessary to grip the connecting web l9 with apair of pliers and exert a slight outward pull thereon against thetension of the springs 26 until the teeth on the attaching plate andstrike plate become disengaged when, by moving the strike plate l6either vertically or laterally of the door jamb, the opening l3 in thestrike plate may be properly alined with the sliding lock bolt of thedoor look, as will be readily understood. When the proper adjustment ofthe strike plate has been effected, the springs 2-1 will automaticallyreturn the strike plate iii to normal position and in which position theteeth will interengage and prevent further movement of said strikeplate.

While it is preferred to make the attaching plate in two sections, itwill, of course, be understood that said attaching plate may be ofintegral 20 construction, if desired. It will also be understood thatthe lcck strikes may be made in different sizes and shapes toaccommodate any style or type of door without departing from the spiritof the invention.

Having thus described the invention, what is claimed as new is:

1. A look strike comprising an inner attaching plate, an outer strikeplate having face to face engagement therewith, and yieldable means for3 holding the strike plate in a set position and permitting shiftingthereof to another set position in its initial plane.

2. A look strike comprising an inner attaching plate and an outerhorizontally and longitudinally adjustable strike plate fitting againstthe outer face thereof, said plates having confronting faces providedwith inter-engaging members, pins extending through said plates, andsprings surrounding the pins for normally and yieldably 4 holding thestrike plate in a set position.

3. A look strike comprising a body having a seating recess and providedwith longitudinal and transverse teeth, a strike plate adjustablymounted within the seating recess and provided with teeth adapted toengage the teeth on the body, pins secured to the strike plate andloosely extending through the body plate, and coiled springs surroundingthe pins for normally and yieldably holding the teeth on the strikeplate and the body 50 in engagement with each other and maintaining thestrike plate in an adjusted position.

4. A look strike comprising a body having a seating recess formedtherein and provided with longitudinal and transverse teeth, there being55 spaced openings formed in the body and extending through said teeth,a strike plate adjustably mounted within the seating recess and providedwith teeth coacting with the teeth on the body,

pins secured to the strike plate and extending through the openings inthe body and having heads at their free ends, washers fitted around thepins and spanning the openings in the body, and coiled springs fittedaround the pins and bearing against the heads of said pins and theadjacent washers to maintain the strike plate in an adjusted position.

5. A look strike comprising a body having a laterally extending tongueand provided witha seating recess and a bolt receiving opening in therecess, the inner wall of the recess being formed with longitudinal andtransverse teeth about the bolt receiving opening, there being spacedfastener receiving openings formed in the body above and below the boltreceiving opening and intersecting the adjacent teeth, a strike plateadjustably mounted in the seating recess and provided with correspondingteeth for engagement with the teeth on the body, pins threaded in thestrike plate and extending loosely through the openings in the body andformed with heads at their free ends, washers fitted over the pins andbearing against the rear face of the body about the fastener receivingopenings therein, and a coiled spring interposed between each washer andthe head of the adjacent pin.

6. A lock strike comprising a body having a seating recess therein andprovided with a bolt receiving opening and teeth about the opening, astrike plate adjustable longitudinally and laterally within the seatingrecess and provided with teeth inter-engaging the teeth of the body,pins rigidly secured to the strike plate and extending loosely throughthe attaching plate, and resilient means carried by the pins fornormally and yieldably holding the strike plate in an adjusted positionwith the teeth on the strike plate and attaching plate in grippingengagement with each other.

7. A look strike comprising a body formed of rigidly united front andrear plates, the front plate being formed with an opening exposing aportion of the rear plate and together therewith providing a seatingrecess, the exposed portion of the rear plate having a roughened surfaceVisible through the opening of the front plate, an adjustable strikeplate seated in said recess and provided with a roughened surfacecoacting with the roughened surface on the rear plate, guide pinssecured to the strike plate and passing loosely through openings in therear plate, and springs surrounding the pins and bearing against therear face of the rear plate for normally and yieldably holding saidroughened surfaces in gripping engagement with each other to maintainthe strike plate in an adjusted position.
